I have an HDMI switch that starts acting up if the power cable gets loose. Why does the power cable get loose? No idea, but it’s also a cheap nobrand switch. This probably isn’t your issue, but try pushing the barrel connector in more or try a power supply that supports a higher current (same output voltage). I only mention it because I only managed to “fix” my switch by noticing it was just a mm out of the jack.

This is great! If I ever get a minute from playing Balatro from the Steam sale I’ll try some out!

I saw this a bit ago and I think it’s really creative. I won’t use it though because I’m not a cat person. If there are any other unique ones out there (not just a distro logo with flair), I’d be interested.
